Application filed January 27,1905. Renewed January 26, 1906. Serial No.298.063.

.To all whom may concern:

Be it known that I, JAcKsoN FLFRAZEE, a

citizen of the United States, 'residin in the cit and county of SanFrancisco, tate of Ca ifornia, have invented certain new and usefulImprovements in Multiple Ball-Bearing Supports for Punching-Bags; and Ido hereby eclare the followin to be a full, clear, and exact descriptionof t e same. 4

The present invention relates to an im- [proved form of support forunching-bags,

the working parts of which s all be so constructed as to provideball-bearing surfaces therebetween wherebyfriction is materially reducedand the several parts permitted free and independent movement inaccordance with the direction of strain exerted thereon by the swing ofthe punching-bag suspended therefrom.

To comprehend the invention, reference should be had to the accompanyingsheet of drawings, wherein t :Figure 1 is a view illustrating the assembled support secured to an overhead beam or ceiling, the suspension-cordattached thereto at its upper end bein partly broken and cured thereto,

disclosinga section of t e punching-bag 'se- Fig.2 is a detail view, thesupporting base-plate, with its de ending extension, bein sectionedvertical y in order to illustrate t e connection of the rotatable stemthereto; and Fig. 3 is a plan view of the.

su portingrbase-plate.

n the awings the numeral 1 1s used to indicate any suitable form of asupporting base-plate, which base-plate is attached to an overhead beamor ceilin by screws 2 or any other desired form of astenmg means.

' The base-plate 1 is 1pirovided with a depending extenslon 3, Wit

n which-are located the wear-cups 4 4'.

the cones 6 6. Said cones are fitted on the rotatable stem 7, whichextends through the depending extension 3 and is held in place by meansof the nut 7 secured to the upper end thereof and located within theextension 3.. A swivel connection is thus made with the extensions 3 ofthe base-plate 1.

punching-ha 10 without These wear-cu s 4 4 pro- .vide circular seats forthe den le-series of bearing-balls 5 5, on which rest, respectively,

The projecting or lower end 8 of the rotatable stem 7 issomewhatenlargedand is formed with an eye 8'. open portion of the enlarged end or head8'is arranged a series of balls 9, which act as a ball-bearing for thehook member 9, fitted or secured within the e e 8. By this form ofconnection between t e hook member and the eye 8 there is provided aball-bearing,

joint which allows for the free movement of 60 the swin of the anger oriability of the same inding or cramping, thuspermitting of a uniformmovement bein imparted to said punching-bag. To the 00k member 9 isattached a depending holder 1 1, which holder receives and retains theupper end portion of the suspension cord or rope the hook member 9'during 1 12, to the lower end of which cord or rope there isattached thepunching-bag 10.
